I got your point . I understand why 477 send failed message is coming . Lets I am not using TCP . I am using UDP . my question is how I will use a single DB behind a cluster of opensips . Is this possible in UDP . I dont think so . In UDP i may get "408 request timeout" message from opensips node .
Lets say . I have a client and I have given a domain to that . against that domain there are 2 opensips node and both sharing same DB and running in db_only mode . My UAC is behind NAT off-course . According to you I cant use this scenario if my UAC is behind NAT . If opensips nodes and UAC can communicate internally inside a LAN then its possible . Please correct me if I am wrong . *Thanks & Regards* *Sasmita Panda* *Network Testing and Software Engineer* *3CLogic , ph:07827611765* On Tue, Jul 25, 2017 at 6:38 PM, Bogdan-Andrei Iancu <bog...@opensips.org> wrote: > Sasmita, > > OpenSIPS can open a new TCP connection towards an UAC IF: > 1) the registered IP is public > 2) the UAC is not behind a NAT. > > The 477 reply is generated by the inability of OpenSIPS to open a TCP > connection - you can see some error messages into the logs too. > > Regards, > > Bogdan-Andrei Iancu > OpenSIPS Founder and Developer > http://www.opensips-solutions.com > > OpenSIPS Bootcamp 2017, Houston, US > http://opensips.org/training/OpenSIPS_Bootcamp_2017.html > > On 07/25/2017 02:53 PM, Sasmita Panda wrote: > > Is there any way opensips nodes will be connected in TCP ?
